Specification of Letters Patent. Patent d J 27 192 Application filed February 13,1918. Serial no. 216,903.

To all who met may concern: 7 Be it known that I, J FRANK ALLARD, a citizen of the United States, residing in Brooklyn Borough, in the county of Kings, city and tate of New York, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a specification. a

This invention relates to tabulating mechanism, in which provision is made for mechanically setting the column-stops to effective positions in a variety of groupings so that when changing from one class of work or printed form to another, a corresponding change in the column-stops may be effected by simply adjusting a singleopart. A ma.

chine of this general character is illustrated in the patent to McLaughlin, No. 941,166.

In said patent, the column-stops form the forward ends of blades or carriers which extend rearwardly and which carry lugs for engagement by an assortment of spurs, which are carried upon a revoluble shaft. By turning the shaft to different set positions, different groups of spurs may be brought into use, and hence different columnstops may be mechanically selected; those stops which are no longer to be used being returned automatically topositions of disuse.

Owing to the construction of the columnstop blades or carriers, which extend rearwardly a considerable distance at the back of the machine, it is found that it is impracticable to use the McLaughlin mecha nism in machines where other necessary devices are placed at the back of the typewriting machine in proximity to the carriage, as, for example, adding attachments, such as are used in the well-known Underwood- Hanson combined typewriting and adding machine. An object of the invention, therefore, isto simplify and improve the columnstop' mechanism, especially with a View to making the mechanical selecting, devices more compact, and also with a view to arranging them in such position that the use of other mechanisms at the back of the type writer carriage is not precluded.

Instead of sliding the column-stops, 1 pivot the same, and these pivoted stops extend in a row along the back of the carriage and close thereto. The stops may extend rearwardly from their pivots and may be very short, thus making a compact structure. They are normally elevated positions, but any one may be swung to such a position that it can be reached by any of the decimal-tabulator stops which are usually arranged at the back of the machine and are liftable by individu'al'keys. For compactness, the spur-carrying shaft, which controls the positions of the column-stops. may extend along the machine back of the carriage and above the column-stops, and the spurs upon said shaftvmay engage arms which extend up from the column-stops. Hence, upon rotating the shaft, predetermined arms are pressed back and their stops are depressed to workingpositions, For convenience in setting the shaft, it may be connected by any suitable means, as, for example, a chain and sprockets to a finger piece arranged upon the carriage nearer the front of the machine; and an index and scale may be provided to guide the operator in setting the same. In place of arranging four set positions, as in said McLaughlin patent, I have illustrated, for convenience, a shaft having only two set positions, this being intended to represent a shaft having any desired number of set positions.

Other features and advantages will herepart-sectional side elevation in illustrated has a non-shifting carriage and is provided with the usual decimal tabu lator keys 10, which are arranged upon the forward ends of levers 11, which are adapted to elevate individual decimal-stop-rods 12 mounted at the rear of the machine; each stop-rod being capable of operating through a universal bar 13 to pull down a. link 14, which, by means of. a lever 15, will elevate a letter-feeding rack 16 carried upon the typewriter carriage 21, to release said rack from the control of the usual pinion 17 and escapement wheel 18, so that the carriage may run along until arrested by. means of the engagement of the decimal-stoplt) at the topof a rod 12 with the succeeding set columnstop 20, which is provided upon said carriage. As usual in said Underwood machine, said carriage-escapement wheel 18 is controlled by dogs 22, which are operated by a universal bar 23, the latter being operable by any of the type-bars 24, as they swing towards the platen 25 which is mounted upon the carriage 21, aforesaid.

The column-stops 20 are shown pivoted upon a rod 26, which. is fixed upon the back of the carriage, the stops extending rearwardly from the rod and each one having a spring 27 which keeps it in elevated position of disuse. These stops may work in a rack-guide or comb 28, which may form part of a bar 29 secured to the rear of the typewriter carriage by arms 29 extending rearwardly therefrom. At its rear end, the bar 29 contains said springs 27, which may be helical compression springs arranged in seats 30 carried in the bar 29. The rod 26, which carries the column-stops, may be arranged close to the rack 28, and, for com venience in arranging the column-stops thereon, may be detacha-bly held in brackets 26, secured to the arms 29 by screws 31.

F or setting the column-stops, they are provided each with an upwardly-extending arm 32 adapted to be engaged each by its corresponding spur 33, the latter carried upon the revoluble shaft 34, and constructed so as to be'settable at letter-space or other intervals, and operating as set forth in said patent.

When any spur 33 engages the corresponding upstanding arm 32 to rock the same backwartdly, it thereby depresses the column-stop from its ineffective position, as at Figure 3, to its effective position, as at Figure 2. As many arms 32 will be. depressed as are engaged by cams or spurs 33 along the shaft 34, which spurs operate upon the principle set forth in said patent. The spurs 33 at Figure 2 lock the arms 32 in abnormal positions, because they impinge thereon at dead center, but upon a succeeding quarter revolution of the shaft 34 the arms 32 will be released from the spurs, and the springs 27 will return thecolumn-stops-20; a new set of arms 32 being engaged by the remaining spurs 33 upon the further quarter rotation of the spur-shaft 34, thereby a new set of column-stops 20 being depressed to working positions.

A finger-piece 35 may be journaled upon the carriage near the front of the machine and connected by sprockets 36, 37 and a chain 38 to the spur-shaft 34; and the fingerpiece may be connected to a. notched detent wheel 39 controlled by a spring-pressed de tent 40 also mounted upon the typewriter carriage; there being advantageously twice as many notches 41 as there are effective positions of the spur-shaft 34. For convenience there may be provided at any suitable place, such as the detent wheel 39, a scale having numbers thereon, one for each effective position of said spur-shaft. The scale indication to be read may be shown by a pointer 42 beside the scale. The scale herein shown may comprise the letters B, to indicate a setting of the stops for billing, and I to indicate a setting for inventory. The extra notches on the notched wheel are used to hold the spur-shaft in idle positions between its effective positions, in which idle positions all the setting arms are ineffective and all of the stops are retracted.

Since the machine herein illustrated has a non-shifta'ble platen, the shaft 34 may be journaled in brackets 43 and 44 screwed to the platen frame, the latter bracket also including an enlarged portion 45 forming a bearing for the sprocket 36. If the platen frame is shiftable, the mounting of the shaft 34 and some other parts may be suitably modified.

It will be noted'that each operating arm or spur 33 comprises a hub 46 by which it is mounted on the shaft 34, and that each hub may comprise one or more of the spurs 33. The column-stops may be spaced at letter-space intervals, in which case there is a complete array of stops on the carriage, and the stops, which are to be made effective, may be selected by merely positioning the spurs along the shaft 34 by their hubs. The column-stops 20 are prevented from being thrown out of the comb 28 by thesprings 27, because their arms 32 will strike against either the hubs of the spurs 33 or against the shaft 34 itself before the stops rise clear of the comb 28.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others. Having thus described my invention, 1 claim:
